Snoopy to the rescue (Random House, 1984)

[toinet]

Woodstock is missing! BIRDNAPPED!
Can Snoopy, the Super Sleuth, rescue his feathered friend from the Castle of Danger?


PROTECTION TYPE
On a standard DOS 3.3 16-sector disk, the final header markers have been changed:
- D5 AA 96 AA DE
- D5 AA AD DE AA


DISK COPY
Launch Advanced Demuffin
Insert the Snoopy disk into drive 1
Press B to boot
Copy both sides of the disk

Note: I think side 2 is a backup of side 1


REMOVE THE PROTECTION
We need to apply the standard final markers values at the right places.
Launch your favorite disk editor
- T0/S3/91: AA => DE
- T0/S3/9B: DE => AA
- T0/S6/AE: AA => DE
- T0/S6/B3: DE => AA


Reboot and... enjoy and... rescue Woodstock
